klampt.vis.camera module¶
This module defines a basic set of 3D cameras that can be controlled by a GUI.
-
class
klampt.vis.camera.
free
[source]¶ Bases:
object
A free-floating camera that is controlled using a translation and euler angle rotation vector.
-
- pos
camera center position
-
- rot
euler angle rotation
-
- ori
orientation matrix type (see
orientation_matrix()
)
-
-
class
klampt.vis.camera.
orbit
[source]¶ Bases:
object
An orbit camera that is controlled using a rotation, target point, distance, and orientation.
-
- tgt
target point (in world coordinates)
-
- rot
euler angle rotation (roll-pitch-yaw entries relative to default view with fwd = +y, right = +x, up = +z)
-
- dist
target distance
-
- ori
orientation matrix type (see
orientation_matrix()
)
-
matrix
()[source]¶ Returns the camera transform. Applying this transform converts points in OpenGL camera coordinates (x right, y up, -z forward), to points in world coordinates.
-
set_orientation
(R, ori=None)[source]¶ Sets the orientation of the camera to the so3 element R.
If ori is provided, it is an orientation list (e.g., [‘x’,’y’,’z’]) that tells the function how to interpret the columns of R in terms of the right, down, and fwd axes of the camera. Its default value is None.

orientation_matrix
(axis1, axis2, axis3)[source]¶ Returns the matrix that maps the camera’s identity coordinate system (right,down,forward) to world axes 1,2,3 (assuming no camera translation).
Each axis can be either a 3-tuple or any element of [‘x’,’y’,’z’,’-x’,’-y’,’-z’]

class

target
[source]¶ Bases:
object
A look-at camera that is controlled using a translation, target point, and up vector
Attributes:
pos: camera center position
tgt: target point
up: up direction
